(EPECECATION forming part of Letters Patent No. 303,990, dated August 26, 1884.

Application filed May 3l, 1884. l (No model?) To ZLwwm t may concern.-

Be it known that l, J oHN W'. Davis, a citizen ot' the ifnitcd States, residing at Fairfax, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Plowsr; and Ido hereby declarethat the following is a i'ull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to that class of plows in which the beam is adapted to be adjusted to regulate the elevation of its front end; and its object is to provide simple and improved means for securing the standard to the moldboard and landsidc, and for effecting a couvenient and scc-ure adjustment of the beam n p on the standard.

To this end my invention consists substantially in providing` suitable braces connecting the inoldboard and landside, through which braces the standard passes and is secured, and in pivoting the beam to the top of the standard, suitable devices being provided upon the latter to secure the lower end ofthe beam bclow the pivot. in the position to which it has been adj usted as will be hereinal'teimore f ull y set forth.

In the drawings, Figure 1 is a perspective view illustrating my invention. Fig. 2 is a side elevation. Fig. 3 is a vertical transverse sectional view taken on the planeet' the standard.

Corresponding lparts in the figures are dcnoted by the saine letters ot' reference.

Referring` to the drawings, A desiguales the mold-board, and D the landside, which parts may be of any suitable construction.

C is a transverse brace secured to thc lower portion of the rear face of the mold-board, and near the outer edge thereof, as shown at c, and from thence extending across to about the center of the landsidc, and secured thereto, as shown at c.

D designates another angular brace, which is secured to the rear iace ot' the moldboard at its frontend, d, and has its rear end, d', secured to the rear end of the landside. This brace D is arc-hed or formed so that it extends over the transverse brace C, and the said braces are thus relativelyY disposed at an angle to each other. Suitable openings or perforations, cl di, are respectivelyprovided in the. braces and on the same vertical plane, which openings receive the standard E, as shown. The lower portion of the standard, which passes through the brace' C, is screw-threaded, an d receives two nuts, F G, working, respectively, above and below the brace C, and serving to retain the standard down in position. A. collar, H, is provided on the standard at a point just above the brace D, and has its undersurface provided with radial serrations 71, which engage correbrace D. By this arrangement, when the standard is drawn dow-n by the action of its securingnuts, these serrations are brought into engagement, and the standard is secured in position and against. accidental vertical movement or turning. The standard is p rovided with a top flat portion, c, to which is pivoted the beam I. as shown at t. rEhe rear end, i', of the beam extends some distance below this pivot, and is provided with a segmental slot, fifi, which receives a transverse screw bolt, J, working` through the top portion of the standard. Upon the inner end ot this screw-bolt is provided a clamp-nut, K, which binds against the 'i'acc of the beam, and reta-ins it in the position to which it has been adjusted. Byoperating the screw-bolt the nut may be loosened sufficiently to permit ofthe adjustment oi' the beam upon its pivot, after which the bolt is again screwed up to clamp the nut against the beam. The nut K is secured against rotary movement during the operation ot' the bolt J by its engagement with the top edge, a, ofthe mold-board, the relative arrangement being such that when the standard is drawn down and secured by the nuts F and G the edge ot' the nut K is locked into engagement with the top edge ot' the mold board, as illustrated in Fig. lof the drawings.

The operation and advantages of my invention will be readily understood from the foregoing description and annexed drawings. The construction is simple, and permits ot' the convenient and ready adj ustmcnt of the beam. It is obvious that inyinvcntionis adapted for a p plication to various kinds of plows, either walking or sultry plows, and that it is suscepsponding scrrations, di, on the top face of the IOO tible of regulation for one, two, or any other desired number of horses.

In my invention the regulation of the depth of cut is readily and conveniently effected by simply adjusting the rear end of the beam, in lieu of adjustment of the draft at the front end of the beam, as heretofore done, and the improved arrangement serves to materially lessen the draft.

I claim as my invention- 1. The combination, in a plow, of the moldboard, the standard, adjustable devices for removably securing the standard in position, the beam pivoted to the top of the standard, and having the end slot, the adjusting-bolt passing through the standard and through this slot, and the clamp-nut engaging the edge of the mold-board when the standard is secured down in position, substantially as set forth.

y2. The combination, in a plow, of the moldboard, suitablebraces having perforations, the

standard having a screw threaded portion passing through these perforations, securingnnts upon the standard, the beam pivoted to the standard and having the segmental slot, the transverse adjustingbolt, and the nut thereon, substantially as and for the purpose set forth.

3. The combination of the mo1dboard and landside, braces connecting the same and provided with perforations, one ofthe braces being provided with a serrated face, the standard passing through said perforations and having the serrated collar, and devices forsecuring the standard to the braces, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN W. DAVIS.
